tcsh setup in Linux Follow the steps in WSLubuntu to install Ubuntu Linux inside your Win10 The following also apply to any Linux (except 'sudo apt' steps). 7. Now install tcsh , xterm, gfortran, make in Ubuntu: sudo apt install tcsh sudo apt install xterm sudo apt install make sudo apt install gfortran ( and similarly for any other missing program, like zip ) 8. Download the zip file: http://www.math.utk.edu/~vasili/FTP/setup-scripts_few.zip and save it in your WSLubuntu (shared) folder. 9. Click Ubuntu in Win to get a bash shell. In it: cd shared unzip setup-scripts_few.zip cd setup-scripts_few Read the 0readme.txt file: vi 0readme.txt which describes how to set up tcsh and scripts. 10. Finally to switch from bash to tcsh: echo "#--- start tcsh ---" >> ~/.bashrc echo "echo '... starting tcsh ... then do: ss' " >> ~/.bashrc echo "tcsh" >> ~/.bashrc Then click on Ubuntu again, another bash terminal will pop up, and it will switch to tcsh, my favored shell. At this point you have Linux with tcsh and fortran compiler!
